To find the experimental probability of landing on white, you can use the formula:
\[ P(\text{White}) = \frac{\text{Number of times white was landed on}}{\text{Total number of spins}} \]
From the information given, the number of times white was landed on is 45, and the total number of spins is 150.
Now, plug the values into the formula:
\[ P(\text{White}) = \frac{45}{150} \]
Now, simplify the fraction:
\[ P(\text{White}) = \frac{45 \div 15}{150 \div 15} = \frac{3}{10} \]
Next, to express the probability as a percentage, multiply by 100:
\[ P(\text{White}) = \frac{3}{10} \times 100 = 30% \]
Thus, the experimental probability of landing on white is 30%.
